In the United States, a German wolfdog disappeared from his owner's boat and fell into the sea. He drifted at sea for five weeks. During the period of disappearance, the owner was very worried about the safety of the puppy. When the owner gave up hope, US military personnel found that the puppy was alive and well on the coast of California, which made the owner very happy.

However, how the moon survived during this period also made the owner and the search and rescue team very curious. Search and rescue personnel speculated that the moon may have survived by eating dead seagulls, fish carcasses, and rats during this period. The moon swam a distance of nearly 1,600 meters. This arduous journey was probably only known to the moon, but when the owner met the puppy, the heavy stone in the owner's heart was also relieved.
